摘要
目的:观察粘接性夹板固定慢性牙周炎患者松动患牙前、后龈沟液中牙龈卟啉单胞菌和血链球菌的数量变化及牙周状况,以期为评价临床疗效提供参考。方法:选择慢性牙周炎患者19例(76颗松动患牙),记录比较牙周治疗前(基线)、经牙周基础治疗后,采用粘接性牙周夹板固定修复后3、6、12个月的牙周状况(菌斑指数,探诊出血指数、探诊深度、附着丧失)变化;采用电化学测菌法检测龈沟液中牙龈卟啉单胞菌和血链球菌的数量变化;评估患者对夹板固定后美观、功能等方面的满意度。结果:经统计学分析,牙周夹板固定后各时间点的牙周临床指标间差异无统计学意义;牙龈卟啉单胞菌、血链球菌数数量较初诊基线显著减少,差异有统计学意义(P<0.05);牙周夹板固定期间差异无统计学意义(P>0.05)。患者对牙周夹板的美观、咀嚼、发音及舒适的满意度为84.2%以上。结论:慢性牙周炎经牙周基础治疗后,采用粘接性牙周夹板可有效固定松动患牙,使之恢复咀嚼功能;加强口腔健康指导,定期实施牙周维护是影响其治疗效果的重要因素。
Objective： To investigate the amount changes of P.gingivalis and S.sanguinis in gingival crevicular fluid of chronic periodontitis patients treated with adhesive periodontal splint. Methods： Nineteen aged chronic peridontitis patients （76 teeth loosen teeth） were included. The clinical parameters, including plaque index, gingival index, probing depth and clinical attachment loss were recorded at baseline, after periodontal treatment, 3, 6 and 12 months after splint treatment. The changes of P.gingivalis and S.sanguinis amounts in gingival crevicular fluid were observed using electrochemical method. The satisfaction, appearance and function were evaluated. Results： The results showed that no statistical siguificances were observed in clinical parameters during splinting. The absolute number of Porphyromonas gingivalis and Streptococcus san- guinis decreased after splinting compared with the initial visit, and no significant change was observed during the entire observation period after splinting. The satisfaction with aesthetics, chewing, pronunciation and comfort was above 84.2%. Conclusion： For chronic periodontitis, after periodontal treatment, adhesive periodontal splint treatment could effectively fix loosen teeth, obtaining good chewing function. In addition, regular periodontal maintenance should not be ignored to achieve satisfactory results.
